Dual Window Wideband Couplers are high quality components designed to divide or combine optical signal in optical fiber system.

These devices are fabricated by using the fused bi-conical taper (FBT) process are reliable over wide range of temperature.

The operating wavelength is 1310nm and 1550nm and the passband is 80nm.

The coupling ratio can range from 1:99 to 50:50.

Various packaging and pigtailing configurations can satisfy our customer's requirements.

Multimode couplers precisely divide light signals between two multimode fibers. The couplers are bi-d-irectional in performance for either power splitting or Combining and operate 800nm to 1300nm.Multimode couplers are offered with standard 50/125μm or 62.5/125μm fiber. The devices can beassembled into miniature or ruggedized packages and can be terminated with industry standard multimode connectors.
